DETAILED DESCRIPTION

An automatically adjustable seating apparatus is described. The term automatically adjustable, when used to described the seating apparatus, is intended to mean that the seat is not manually adjusted by an operator, i.e., no physical pushing or pulling of the seat is required by the operator. Rather, the seat is automatically adjusted through an interaction with a controller that controls the seat position. The automatically adjustable seating apparatus can be configured, in a first arrangement, as two seats arranged back-to-back. The two seats have bottom portions and back portions. The two seat bottom portions are slideably attached to a frame and are moveable by automatic adjusters between retracted positions and extended positions. When both bottom portions are in their retracted positions, the automatically adjustable seating apparatus is configured as two seats back-to-back. When both bottom portions are in their extended positions, the automatically adjustable seating apparatus is configured as a substantially flat surface.

A second automatically adjustable seating apparatus is also described. The second automatically adjustable seating apparatus can be configured, in a first arrangement, as two seats arranged back-to-back. The two seat portions have bottom portions and back portions. The first seat bottom portion is slideably attached to a frame and is moveable by an automatic adjuster between a retracted position and an extended position. When the first seat bottom portion is in the retracted position, the second automatically adjustable seating apparatus is configured as two seats back-to-back. When the first seat bottom portion is in the extended position, the second automatically adjustable seating apparatus is configured as a substantially flat surface.
